About IPsec Tunnels
IPsec stands for IP Security, a set of protocols that suppor ts secure exchange of IP packets at the IP layer.
IPsec is deployed widely to implement Vir tual Private Networks (VPNs). See

information.
IPsec suppor ts two encr yption modes: Transpor t and Tunnel. Transpor t mode encr ypts only the data por tion
(payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encr ypts both the
header and the payload. On the receiving side, an IPsec-compliant device decr ypts each packet. Motorola

Routers suppor t the more secure Tunnel mode.
Motorola Netopia® Embedded Software Version 8.7.4 offers IPsec 3DES encr yption over the VPN tunnel. DES
stands for Data Encr yption Standard, a popular symmetric-key encr yption method. DES uses a 56-bit key.

Routers offer IPsec 3DES (triple DES) encr yption as a standard option. Some models
suppor t built-in hardware acceleration of 3DES encr yption at line speeds.
Internet Key Exchange (IKE) is an authentication and encr yption key management protocol used in conjunction
with the IPsec standard. IPsec key management offers a wide variety of options which are explained in

About L2TP Tunnels
L2TP stands for Layer 2 Tunnelling Protocol, an extension to the PPP protocol. L2TP combines features of two
other tunneling protocols: PPTP and L2F. Like PPTP, L2TP is a Datalink Encapsulation option in Connection
Profiles. It is not an option in device or link configuration screens, as L2TP is not a native encapsulation.
Consequently, the Easy Setup Profile does not offer L2TP datalink encapsulation. See the
other tunneling protocols: PPTP and L2F. Like PPTP, L2TP is a Datalink Encapsulation option in Connection
Profiles. It is not an option in device or link configuration screens, as L2TP is not a native encapsulation.
Consequently, the Easy Setup Profile does not offer L2TP datalink encapsulation. See the
for information on creating Connection Profiles.
